I Application filed May 29, 1924. Serial 110,716,712.

To all whom it may con/0 7%.",

Be it known that I, WVALTER J. KIRKHAM, a citizen of the United States, residing at Helena, in the county of Phillips and State of Arkansas, have invented a new and use ful Water-Closet, of which the following is a specification.

This invention aims to provide novel means whereby a connection between a closet bowl and ,a flush tank, and a connection between the valve seat and the flush tank may be effected, withoutresorting to flush ells, 'spuds, lock nuts and the like, which tarnish, accumulate dirt and lend complications of various sorts.

It is within the province of the disclosure to improve generally and to enhance the utility of devices of that type to which the invention appertains.

Although a preferred form has been shown in the drawings, it will be understood that a mechanic, working within the a fragmental plan showing a scope of what is claimed,'may make changes, without departing from the spirit of the invention, or placing the utility of the device in jeopardy.

In the drawings :,-F igure 1 is a vertical sectional View disclosing a device constructed in accordance with the invention, some parts being in' elevation; Figure 2 is a section taken through the valve seat and attendant parts; Figure 3 is an elevation disclosing the valve seat; Figure 4% is a plan of the valve seat. Figure 5 is portion of the bottom of the flush tank.

The numeral 1 marks a closet bowl having an upstanding integral neck '2 provided with a tapered bore 3 wherein isseated a conical gasket 4:, which may be made of lead, if desired. The flush tank is marked by the numeral 5, and water is furnished to the tank through a supply pipe 6 enclosed within a casing 7 of'tubular form, comprising telescoped parts 8 and 9, held against relative movement by a set screw 10.

The numeral 11 designates av Valve seat including a body 12 having a rim 1 1 equipped with outstanding lugs 15, adapted to cooperate with a spanner wrench, or like tool, whereby the valve seat may be rotated for a purpose tobe explained. here inaf ter. pered foot 16 provided with cam ribs 17 on its sides, theupper edges of the ribs being inclined, as at 18, circumferentially The valve seat 11 includes .a ta-- of the "foot 16. There is ashoulder 19 at the place where the foot 16 of the valve seat 11 joins the body 12 of the valve seat. The valve seat 11 is provided in its upper end with a recess 20, and has a tapered bore 21 communicating with the recess. The

recess 20 is adapted to receive a float valve 22 operated by any common means 23. The valve seat 11 is equipped with an offset arm 24 provided with a nipple 25 adapted to receive a pipe 26 discharging through a passage 27 in the arm 24;, into the bore 21 of the valve seat, below the valve 22, when the valve cooperates with the recess 20. The pipe 26 communicates with the ball cock (not shown) and serves as a refill for the siphon of the bowl 1, in a way well understood by those skilled in the art.

The bottom of the flush tank 5 is provided with a tapered spout 28 seated within the gasket 4. The spout 28 is equipped with. internal circumferential grooves 29, shaped and adapted to receive the cam ribs 17 of the valve seat 11, a gasketl30, made of lead or any other suitable material, surrounding the foot 16 of the valve seat 11 and bound between the shoulder 19 and the bottom of the tank 5. In order that the cam ribs 17 may be inserted into the circumferential grooves 29, the bottom of the tank 5 is provided, as shown in Figure 5, with slots or notches 31 communicating with the grooves 29 and with the opening 32 in the tank bottom 5, through which the tapered foot 16 of the valve seat 11 extends.

In practical operation, the foot 16 of the valve seat 11 is inserted into the spout 28 011 the bottom of the tank 5, the ribs 17 passing downwardly into the grooves 29 through the notches 31. A spanner wrench or like tool is applied to the lugs 5 of the valve seat 11, and the seat is rotated,

theribs 17 and the grooves 29 causing the seat 11 to move downwardly, the gasket 30 being bound tightly between the bottom of the tank 5 and the shoulder 19 of the valve seat 11.

hat is claimed is Y In a device of the class described, a flush tank comprising a bottom having an in-- tegral spout provided in its interior with circumferential grooves, the upper walls of which are formed by the bottom of the tank, the bottom being provided with notches communicating with the grooves,

and a Valve seat extended into the spout, the seat having lateral cam ribs insertable through the notches into-the grooves, the seat having an external shoulder, and a gasket interposed between the shoulder and the bottom of the tank,-th'e ribs cooperating cam-wise with the grooves, when the seat is rotated, to bind the gasket between the shoulder and the bottom of 10 the tank, the gasket and the shoul'derco operating to prevent a distortion of the bottom of the tank, due to the cam action oft-he ribs.

In testimony that I claim the foregoing as my own, I have hereto aflixed my signa- 15 E RoD OATES.
